A hybrid plug-in connector for connecting electrically conductive contacts to a mating plug-in connector has at least two energy contacts for transferring electrical energy and four data contact pairs for transferring electrical signals and/or electronic data, includes a shielding element is formed such that the shielding of a data cable, first of all in the hybrid plug-in connector, and in the connected state of the hybrid plug-in connector to the mating plug-in connector is at least extensively maintained, wherein four data contact pairs are arranged in a principally rectangular insulating body, spatially separated from the energy contacts, the insulating body having an offset in the axial direction relative to the longitudinal axis of the hybrid plug-in connector between the data contact pairs and the energy contacts, such that the hybrid plug-in connector is uniquely positioned on the mating plug-in connector thereof during a plug-in process.
